Ewan Spence has an awesome podcast: The Edinburgh Fringe 2005 Show with MacHomer . MacHomer is this crazy guy who does impersonation of all the Simpsons characters talking about a production of MacBeth. It's hilarious. Ewan does a really good interview.

Actually this is the first podcast I've listened to that's good I think... the other ones I've listened always seem pompous and self-important.

And the MacHomer guy is Canadian :-)

OK, as a public service I'll see if I can find any online sources for the actual MacHomer show...
